Patch-walking is a novel automated patch clamp approach for finding synaptic connections in brain tissue, yielding 80–92% more probed connections than traditional approaches.
The first patch-clamp recordings from single cerebellar granule cells during locomotion reveal that the entire step sequence can be predicted from both excitatory synaptic input and output spikes from a single neuron.
For analyzing time-dependent patch-clamp or patch-clamp fluorometry data of ion channels in terms of Markovian models, the superiority of Bayesian filtering with respect to traditional deterministic approaches is demonstrated enabling more reliable quantification of the parameters.
Direct patch clamp of ependymal motile cilia reveals that voltage-gated calcium channels in the cell body dominate their electrical and calcium signaling properties.
A combination of patch clamp electrophysiology and FRET determine critical interactions between HCN4 channels and the ER resident protein LRMP and suggest a possible mechanism for reduced cAMP sensitivity.

Paracellular, trans-tight junction channels, which communicate between two extracellular compartments without crossing the plasma membrane, are a new class of ion channel with unitary behaviors similar to traditional transmembrane channels.

Single-neuron spikes in a network model of the turtle cortex trigger reliable, yet flexible sequences of activity through a sparse backbone of strong synaptic connections.
A powerful new fluorescence approach elucidates the structural mechanism for a specialized ion channel behavior important for cardiac and neuronal excitability.
